Vertiv Cmrx 45U 24 in 36 in White - CMRX-45U36-W-1224

Vertiv CMRX-45U36-W-1224 45U Rack Enclosure — 36" Deep, Winter White

Overview

The Vertiv CMRX-45U36-W-1224 is a 45U closed rack enclosure finished in Winter White, designed for IT, security, and network equipment deployments where a clean, professional appearance matters — think server rooms, NOCs, and equipment closets that do double-duty as customer-facing or executive-visible spaces. The "W" in the SKU designates Winter White (as opposed to the standard black variant), and the 36" depth gives you room to house full-depth servers, patch panels, and dense cabling runs without forcing compromise on cable management. If you are speccing a new rack row and need to match an existing white-cabinet aesthetic or meet a facilities standard, the CMRX-45U36-W-1224 is the variant to order.

Vertiv's CMRX line is a flexible platform: the same family spans 45U, 52U, and 59U heights, and depth options range from 10.5" through 16.25", 24", 30", and 36" — meaning the CMRX-45U36-W-1224 sits at the wider end of the depth range, positioned for high-density equipment. Color and size selections exist within the family, so if your deployment calls for a different height or shallower footprint, a sibling SKU covers it without switching vendors or mount systems.

Key Features

• 45U usable space: 45U gives you room to fully populate a rack row — mix in 1U patch panels, 2U switches, and 4U servers without running out of vertical real estate mid-project. Fewer racks to manage, fewer PDU runs, less floor space consumed.
• 36" depth: Full-depth (36") accommodates contemporary server platforms and UPS units that won't fit in a 24" or shallower cabinet. If you're running Dell R7xx/HPE DL3xx-class hardware plus rear cable management arms, 36" is typically the minimum depth to keep the doors closeable.
• Winter White finish: The Winter White color option is a practical choice when the installation is in a lab, studio, or customer-visible space where standard black racks look industrial. Matches common suspended-ceiling tile colors and blends with bright-lit raised-floor environments.
• Triple mounting compatibility — #12-24 tapped, 3/8" sq. (M6), and Clear: Supporting all three standard rack rail profiles in a single enclosure means you're not locked into a single equipment generation. Legacy gear using #12-24 screws, modern gear shipped with M6 cage nuts, and toolless clip-in panels all mount without adapters or third-party rail conversions.
• Scalable family (45U/52U/59U heights, multiple depths): When a deployment grows, you can add additional enclosures from the same CMRX line — consistent aesthetics, identical mounting compatibility, and matched accessories (doors, side panels, blanks) across the family.

Integration & Compatibility

The CMRX-45U36-W-1224 is compatible with standard 19" EIA-310 rackmount equipment. The three-position mounting compatibility — #12-24 tapped holes, 3/8" square (M6) holes, and Clear (toolless) — covers the full range of contemporary and legacy rack equipment without requiring adapter kits. This matters in mixed-vintage deployments common in security operations centers, where network switches from different eras and manufacturers need to coexist in the same cabinet.

For Vertiv rack enclosure accessories — PDUs, cable managers, blanking panels, and side panels — verify compatibility against the CMRX product line to ensure correct fit. Accessory fitment within the CMRX family is consistent across the height variants (45U, 52U, 59U), so shared accessories reduce procurement complexity across a multi-rack deployment.

Frequently Asked Questions

Q: What mounting hole patterns does the CMRX-45U36-W-1224 support?

A: The CMRX-45U36-W-1224 supports three mounting configurations: #12-24 tapped holes for legacy equipment, 3/8" square (M6) holes for modern cage-nut-based gear, and Clear (toolless) mounting. This covers virtually all standard 19" EIA rackmount equipment without adapter hardware.

Q: What is the difference between the 45U, 52U, and 59U variants in the CMRX line?

A: The CMRX family is offered in 45U, 52U, and 59U heights. The 45U (this SKU) is the most common depth for mid-scale deployments. Select 52U or 59U if you need additional vertical capacity — for example, adding more patch panels, blanking panels, or high-density switching into the same rack footprint.

Q: Does the CMRX-45U36-W-1224 come in black?

A: Yes — the CMRX line is available in both Black and Winter White. The "W" in the model number designates Winter White. If you need the black variant at 45U/36" depth, select the corresponding CMRX SKU without the "W" designator.

Q: Is the 36" depth the only option for the CMRX 45U?

A: No. The CMRX 45U is available in multiple depths within the family: 10.5", 16.25", 24", 30", and 36". Choose 36" (this SKU) when you need to house full-depth servers, UPS units, or equipment with rear cable management arms. Shallower depths suit patch-panel-heavy or network-only deployments with lower rack depth requirements.

Q: What is the manufacturer warranty on the CMRX-45U36-W-1224?

A: Vertiv provides a manufacturer warranty on CMRX enclosures. Contact Vertiv or your procurement channel for the specific warranty terms applicable to this SKU, as duration can vary by region and purchasing agreement.

The CMRX-45U36-W-1224's 36" depth is the spec I'd focus on when evaluating this enclosure for a mixed-hardware deployment. At 36", you have enough room to mount full-depth servers with cable management arms fully extended — something a 24" or 30" cabinet doesn't reliably give you once you account for rear PDU mounting and horizontal cable managers. Winter White finish aside, the triple mounting compatibility (#12-24, M6, and Clear) is what makes this a practical choice when you're populating a rack with equipment sourced from different vendor generations.

Technical Highlights:

• 36" cabinet depth: Accommodates full-depth 2U–4U servers plus rear cable management without door interference — critical for dense security server and NVR deployments.
• Triple mounting compatibility (#12-24 / M6 / Clear): One enclosure handles legacy tapped-hole gear, modern cage-nut equipment, and toolless snap-in panels — no rail adapter kits, no secondary hardware orders.
• 45U height (CMRX-45U36-W-1224): Enough vertical space to house a full NVR stack, PoE switch tier, patch panels, and a rackmount UPS in a single cabinet — reducing the number of discrete enclosures needed per row.

Deployment Considerations:

• Verify ceiling clearance before ordering the 45U variant — at approximately 83–84" of rack height plus base/caster height, clearance is tighter than it appears on a floor plan, especially in raised-floor environments with overhead cable trays.
• The Winter White finish shows dust and cable dressing quality more readily than black — factor in housekeeping practices and whether the environment has regular maintenance cycles if aesthetics are a stakeholder concern.

This enclosure is a solid fit for a security operations center or NOC refresh where the facility has white cabinet standards and where mixed-vintage network and server hardware needs to coexist in a 36"-deep footprint without custom adapter hardware.
